Should positive and negative charge be termed opposites?

AI Thread Summary
The discussion centers on whether positive and negative charges should be considered opposites or complementary. Some argue that while electrons and protons have numerically opposite charges, the terms "opposite" and "complementary" can be subjective. The notion of charges seeking each other is explored, suggesting that they may not be true opposites in every context. The idea that an inherent changing magnetic field produces an electric field, leading to a corresponding negative charge, is introduced, reinforcing the view of charges as complementary rather than strictly opposite. Ultimately, the terminology used may depend on individual perspective, with "charge" being the more descriptive term.

Should positive and negative charge be termed opposites? Maybe they are merely complimentary and this is why they seek each other and are not opposites?

No, an electron and proton have specific charges that can be expressed numerically as opposites of each other.
 
What about if we assume that an inherent changing magnetic field is producing an electric field, as it were, the proton charge, then by conservation of charge there must be a negative corresponding charge; just in this sense, IMHO, they can be complimentary

I'm sure "opposite" is used subjectively, since they are not truly opposite in every aspect. "Charge" is the more descriptive word. "Complementary" is also subjective.

It's all in your point of view. If you use either in conjunction with "charge", you probably couldn't go wrong.
 
Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'
So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
